Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dishwashers, and particularly refers to a cleaning machine for cleaning tableware and fruits and vegetables. Background Art
[0002] Currently, in dishwashers with a relatively large capacity, generally multiple spray arms are provided.
[0003] For example, the Chinese utility model patent "Water flow system for a cleaning machine and cleaning machine" (Patent No.: CN219846437U, Application No.: CN202321315257.7) discloses a structure which is provided with a bottom spray arm, a middle spray arm and a top spray arm, and each spray arm is pumped with water by the same water pump arranged at the bottom of the box body. Since the lower dish rack is the main cleaning area and usually has more tableware placed on it, in order to improve the cleaning effect in this area, the above cleaning machine is also provided with a side spray arm at the side wall of the lower part of the box body for spraying water columns from the side of the lower dish basket.
[0004] However, when there is less tableware placed in the lower dish basket, the water columns sprayed by the above side spray arm will pass through the upper dish basket and impact the inner side wall of the door body, which not only reduces the utilization rate of the water columns sprayed by the side spray arm, but also generates a lot of noise, affecting the user experience. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a cleaning machine that can improve the utilization rate of the side water spray and reduce noise according to the current situation of the prior art.
[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:
[0007] A cleaning machine, comprising a box body, a door body and a side spray arm. An open mouth is arranged on the front side of the box body, the door body is arranged on the front side of the box body and is used to open or close the open mouth, the side spray arm is arranged on the inner side wall of the box body and sprays towards the corresponding lower part of the door body. Spray holes are arranged on the surface of the side spray arm and are arranged towards the door body. A shielding member is arranged outside the spray holes, which can expose the spray holes to allow direct spraying or block the spray holes to disperse the spray water columns, and the shielding member is rotatably constrained on the side spray arm.
[0008] When there are more tableware to be cleaned in the lower bowl basket, manually rotate the shielding member to expose the spray holes. The spray holes can directly spray water jets towards the lower bowl basket to improve the cleaning effect on specific areas in the lower bowl basket. When there are fewer tableware to be cleaned in the lower bowl basket, manually rotate the shielding member to block the spray holes. The water jets ejected from the spray holes are blocked and sprayed onto the lower bowl basket and the surrounding areas in a more dispersed and closer distance, so that the nearby areas can be fully cleaned, improving the utilization rate of the side water jets. Moreover, the water jets will not spray onto the inner wall of the door body to hit the door body, and the noise problem is also avoided.
[0009] Preferably, a base is provided on the back of the front wall of the side spray arm. An installation opening corresponding to the base is formed on the front wall of the side spray arm. A plug-in portion that passes through the installation opening and is rotationally connected to the base is provided in the middle of the shielding member. The base can be constrained on the front wall of the side spray arm by means of screws, buckles, injection molding, etc. With the above structure, it is convenient to realize the rotational connection of the shielding member and keep a proper distance between the shielding member and the spray holes.
[0010] Preferably, a limiting structure for temporarily limiting the positions of the shielding member and the base is formed at the contact surface between the shielding member and the base. After the shielding member is rotated, the limiting structure is used to maintain the relative positions of the shielding member and the base. With this structure, it is convenient to switch the two spraying states of the spray holes by manually rotating the shielding member.
[0011] Preferably, the cross-section of the base is in a U-shaped structure, and the opening of the U-shaped structure corresponds to the installation opening. A first gear ring is provided on the inner wall of the closed end of the U-shaped structure. Correspondingly, the plug-in portion passes through the installation opening and is inserted into the inner cavity of the U-shaped structure. A second gear ring that meshes with the first gear ring is provided at the rear end of the plug-in portion. This structure is beneficial to improve the installation compactness and reliability between the shielding member, the base and the side spray arm, and avoid water leakage.
[0012] Preferably, an elastic member that can always keep the plug-in portion moving towards the base to maintain the meshing and linkage of the first gear ring and the second gear ring is further included. The elastic member is arranged at the front wall of the side spray arm. With the above structure, it is beneficial to the elastic force of the elastic member to keep the sensitivity of the limiting structure.
[0013] Preferably, the inside of the plug-in portion is hollow to form a receiving cavity with a front-side opening. A connecting column that passes through the rear end of the plug-in portion and extends to the front of the receiving cavity is provided at the central part of the base. The elastic member is arranged in the receiving cavity and is connected to the connecting column. Preferably, the elastic member is a spring sleeved on the outer periphery of the connecting column. The first end of the spring abuts against the rear end wall of the receiving cavity, and a end cap is provided at the front end of the connecting column. The second end of the spring abuts against the rear surface of the end cap. The above structure is convenient for installing the elastic member.
[0014] Preferably, a shielding arm extending radially is provided on the outer peripheral wall at the front end of the shielding member, and the injection holes are arranged corresponding to the rotation range of the shielding arm. Preferably, at least two groups of injection holes are provided on the periphery of the installation opening, and each group of injection holes includes at least two injection holes. Correspondingly, the shielding arms of the shielding member are at least two groups. With the above structure, the spray coverage range of the side spray is improved, and thus the cleaning effect is improved.
[0015] Preferably, a water return area is provided at the bottom of the box body, and a bottom spray arm and a middle spray arm are further provided in the box body. The bottom spray arm is arranged at the lower part of the box body and close to the water return area, and the middle spray arm is arranged in the middle of the box body and communicated with the water return area through a water guide pipe.
[0016] Compared with the prior art, the advantages of the present invention are as follows: injection holes are opened on the side spray arm of the present invention, and a shielding member that can expose the injection holes to allow direct spraying or block the injection holes to disperse the injection water column is provided outside the injection holes. When there are more tableware to be cleaned in the lower basket, the shielding member is manually rotated to expose the injection holes, and the injection holes can directly spray water columns at the lower basket to improve the cleaning effect on specific areas in the lower basket; when there are fewer tableware to be cleaned in the lower basket, the shielding member is manually rotated to block the injection holes, and the water columns ejected from the injection holes are blocked and sprayed onto the lower basket and the surrounding areas in a more dispersed and closer distance, so that the nearby areas are fully cleaned, the utilization rate of the side water columns is improved, and moreover, the water columns will not spray onto the inner wall of the door body to hit the door body, and the noise problem is also avoided.
